perfSONAR User Q&A and Other Discussion

[Richard Carlson <>]

Hi John;

Thanks for the logs.  I see from the log extract that your server is  
running 15 sec tests.  However I see other 10 & 60 sec requests, so  
I'm assuming that the 10 sec tests are from people using the command  
line version (10 sec is the default test period) and some other  
servers are scheduling tests via the perfSONAR-Buoy interface on their  
machine.

Here's what I see right now.  Testing to/from MSU is working, but we  
are loosing data.  The current graphs show 7 successful tests from MSU  
--> BNL starting at 1:47 am and ending at 8:27.  The 4:45 am test is  
missing.  The graphs also show 4 tests in the opposite direction  
missing 1, 3, & 6 am.

I also see tests to/from OU with 4 tests from OU -> BNL at 1, 2, 7, &  
9 am with 3 in the opposite direction at midnight, 1, & 7 am.  The  
rest were unsuccessful.

I did notice that you are testing to the psum01 node, which I think  
Shawn setup as the delay server so that's why none of those work.  I  
think you want to test to the psum02 node.

I'm still wondering if your server is just trying to run too many  
tests (19 peers in your config) and I don't know how many other  
servers are requesting tests.  As I see it, we can try reducing the  
number of peers, or we can get the pS folks to help guide us on  
determining why some tests are failing and why some peers aren't  
responding at all.

Jeff/Aaron, what log files should we be looking at to determine what  
is going on?
